As with other toolbars, it can be docked at the top of the ArcGIS window or used as a floating toolbar (see example images below). This toolbar contains a set of tools and menu commands for working with the Arc Hydro Groundwater Data Model. The toolbar appears as follows:

Definition Query Filter

The Definition Query Filter tool simplifies visualizing, analyzing, and working with data within the groundwater geodatabase by filtering a layer based on its FType attribute. For example, a set of wells imported from a state database may contain wells of multiple types (e.g., irrigation, water supply, domestic, monitoring, etc.). The well type is defined in the FType field. When visualizing and analyzing the well data, it might be useful to analyze only certain types of wells. The Definition Query Filter tool makes it easy for users to create filter-selected datasets to include only certain types of data.

By choosing the appropriate option in a combo box located on the Arc Hydro Groundwater toolbar, the layer can be immediately filtered based on its FType attribute.
